Warning Occured

WARNING(OBJ.MCH.KIN6) : D:/Sunday/Body/AAUHuman/Arm/Interface.any(82) : GHMeasure : Close to singular position : Orientation close to Gimbal Lock, i.e., first and third axis of rotation being parallel

Why this warning occured? And will it affect the resultant force?

Hi

No not in this case …

Explanation: the reaction in the GH joint is not made using the reaction forces of the joint itself but by a set of pushing muscles which ensures tha the reaction force fall within the glenohumeral cavity on scapula.

Even if these forces would have been the reaction forces from a spherical joint it would not have had impact since these are forces and not moments. If it would have been moment reactions from a other type of joint with gimbal lock it might have made a difference.

Hope it was not too confusing

Best regards
